['0 (13/ i /IUWL it may concern:

Be it known that I. FREDERICK A. I'IART, citizen of the lhiited States. and resident of New Britain. in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Calculating Machines, of which the following is a specification.

My invention relates to calculating machines and also to combined typewriting and calculating machines.

The main object of the invention, generally stated, is to provide means for preventing unnecessary movements of certain parts of the construction which are or-' dinarily brought about by the travel of the main carriage, and thus reduce wear, strain and noise. incidental to such unnecessary movements and decrease theliability of injury to the machine,

invention is to provide improved means for preventing unnecessary movements-of the auxiliary carriage, cross truck or Jumping.

sary movements of the statev control or change gear mechanism without'preventing a shifting thereof at proper. intervals in the operation of the machine.

To the above and other ends which will,

hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations ofdevices set forth in the following description and particularly pointed out in the appended claims.

In the accompanying drawings, wherein like reference characters indicate corresponding parts in the different mews.

I have shown my invention, in the present instance, embodied in a Remington accounting machine of the character disclosed in the patentto John C. WVahl, No. 1,270,471, dated June 25, 1918, but have shown only so'much of said machine as is necessary to arrive at an understanding of my invention in its embodiment therein. It should he understood, however, thatthe invention is notrestricted toits embodiment in such a machine but may be employed wherever found.availablejin difi'erent makes of calculating machines. v I

"The Remiii" on acco unting machine referred to above includes calculating mechanism attachedto a Remington typewriting machine, the carriage of," which latter has connected'jtheret'o a main calculator carriage or truck,"on which a series of so-called vertic'al totalizer's afremounted. A cross foot or jumping totalilzeris' carried by an auxiliary carriage or cross truck, and automatically operating means are employed for repeatedly picking up and releasing the cross truck and allowing it to return to normal position during the travel of the typewriter and maincarriage or truck across the machine inone'directi'on. These forward and backward movements of the cross truck are sometimes unnecessary, as'will hereinafter appear. Ordinarily when the main carriage is given a continuous movement toward the left itresultsin picking up'the cross. truck as each computing zone is approached and releasing it for return movement when the computing zone is passed, thus causing a series of forward and backward jumping movements of the cross truck with the wear, strain, noise and increased liability of injury incidental to such unnecessary movements. By my present invention I overcome this difficulty by rendering the release of the cross truck by the automatically ac tuated pick-up mechanism ineffective to bring about an unnecessary jumping back or return of the cross truck to normal position. I accomplish this in the present instance under suitable conditions by automat- Ill;

ically throwing a detent or latch into engagement with the cross truck or a part opcratively connected therewith. In the pres ent instance this detcnt is controlled by, and its actuation is incidental to, an operation of either of the ordinary release keys, and also is controlled by the handle of the line spacing mechanism, used also to return the main carriage, and by any of the tabalatoikeys. It follows, therefore, that any of the ordinary means other than the printing keys and space key by which the travel of the main carriage is controlled isoperative to render the detent effective and thereby prevent an unnecessary return movement of the cross truck when it is released from its automatically actuated pickup mechanism.

'lhe ltemington accounting machine referred to above also includes a state changing or change gear mechanism through which motion is transmitted to the register :wheels of tlie'cross totalizer, and which gears are often regulated to beshifted hack and forth by automatically actuatedstate-changing or gear shifting means during the travelof the main carriage. It is sometimesum necessary as when zones without writing therein, to efi'ect back and forth shifting of thegea'r change mechanism. I have, therefore, provided means which, in the present"ins'talice,'l are under control of the same devices umt on;

trol the detent for the cross truck for rendering the automatically operating gear cha nge mechanism ineffective to shift. Said gear change mechanism will therefore, :When for automatic control, remain quiescentf dur ing the travel of the main carriage, when such travel is controlled by" any of said devices; So far as the means herein disclosed for controlling the cross truck against return movement are concerned, they are in the nature of improvements in the construction disclosed in the application of John' H. llarr, Serial No. 568.915, tiled June 17, 1922. In the Remington accounting machine of the character disclosed in the hereinbefore mentioned \Yahl patent, the frame of the typewriting machine comprises a base 9, corner posts 10 and top plate 11. The typewriter carriage, as usual, comprises a front cross bar 12. a rear cross bar 13, and end bars 14 and 15. The carriage is mounted to travel over the top plate and supports a cylindrical plate 16, and is impelled in the direction of its feed by the usual spring drum. not shown. The carriage is controlled in step-by-step letter spacemovements by the usual escapementmechanism which may be said to include the feed pinion 17. A feed rack 18 is carried by the carriage and pivoted thereto at 19; the usual spring (not shown) returning the feed rack into engagement with the feed pinion 1T.

skipping computin A carriage release key 20 ,is provided on the forward end of a release lever 21 pivoted at 22 on the right-hand end bar 15 of the carriage. The rear end of this lever I have bifurcated at 23 to receive a reduced end 24 of the feed rack 18, and form an interlocking connection therewith. A corresponding carriage release key 25 is provided at the opposite side of the machine at the forward end of a lever 26, corresponding to the release lever 21 and I have also coir nected it by an interlocking connection with the feed rack 18.

The usual decimal tabulator mechanism employed in the Remington accounting machine comprises a column stop bar 27 carryingadjusta-ble column stops 28 and supported by bracket arms 29 that project rearwardly from the carriage. Cooperative with the column stops is a series of denominational stops 30,"each forming a forwardly extending projec'tion on a lever '31, pivoted at 3210a Mahala fr'ame33f Said frame is secured by screws 3 to the top plate of the macZhineJand also, to the base by means not shownl The lower end of each tabulator stop lever 31 is connected to a push rod 35, carryinga'tabulator key' 36 at the forward end'there'ofl; Each rod has one end of a contractile 'spring'37 'connectedthereto at 38. The opposite end of each'sprin'g 37 is con- L l L,

ends of piishjrodsiare supported and uided, andwhic'h is detaehably secured to 'tlie base 9. I

addition to projecting each stop into the'path of'the column sto s,', the actuation of eachtabulatorkey 36 e e'c'ts a release of the carriage. Thus, eachg'stop" rod carriesa'collan39 held fast on the rod by a screw 40. Each of these collars constitu t'es an abutmentthat coacts with a universal release bar 41 supported at its ends by arms 42 pivoted on a rod 43; the lower edge portion of release bar 41 being slotted to enable the push rods to extend therethrough. Each arm 42 is connected to a rearwardly extending link -14, connected at its rear end to :1 depending -crank arm =15 on a rock shaft 46. This shaft also carries a crank arm 47, pivoted at 48 to an upwardly extending link 49, which in turn is pivoted at 50 to the frame 51 of a carriage releasing device. Said frame is pivoted at 52 on a bracket 53 secured'to the top plate 11 of the machine frame. The releasing frame carries a journal 54 in which a shaft of the carriage retarding device turns; the forward end of said shaft carrying a pinion 55, and the rear end of the shaft carrying a retarding device 0 erative in the drum 56. The actuation o a tabulator key is effective therefore to rock the frame 51 and lift the pinion This results in throwing the pinion 55 into mesh with the feed rack Ilo llSU

18 and lifting said rack to disengage it from the feed pinion 17. The carriage is then free to travel to the left until arrested by the approaching column stop 28 coacting with the decimal stop 30 that has been projected into the path thereof by the same actuation of the tabulator key 36. When pressure is released from theactuating key 36, it will be returned tonormal position, together witlrthe projected stop 30, by its spring 37, and a spring fi'? returns the universal release bar and the parts controlled thereby to normal position.

The said Remington accounting machine also includes a main calculator/carriage or truck comprisinga bar 58,suitably guided and supported and connected at its ends to travel with the typewriter carriage. .Such connection is' .efl'ected by bracket/iarms-59 secured to'the-end portionsoftheqbar- 58,

and each provided with an zupi'ight slot 60;- that receives; the cylindrical part .of a sh0u ldered and. headed screw, ".61 1 Each screw, '61

is secured ,to :thedepending.tforward end of a bracket arm 62, securefdhto'the typewriter carriage. Th'e'bar 58 carries one or more so-calledvertical totalizers which are detachable therefrom and maybe adjusted to different points along-'saidba'r. Usually a. plurality of such totalizers are employed, as manyqasi thirtyibeing employed zin some instances in long carriage machines. In Fig. 3, I have shown four such totalizers'de'sig' nated respectively by the'reference numeral 63, 64, and 66. 3 Each totalizer comprises a frame which contains the usual equipment including register wheels. 67' and indicating dials 68, which latterdisplay their numerals at sight-openings 69 in the frame-of the totalizer. A-key controlled 'master Wheel 70 operates on the register wheels 67 as they are brought successively-into mesh with the master wheel by the step-by-step movement of the typewriter carriage and the corresponding movement of the main truck or carriage which carries the vertical totalizers. Motion is transmitted from the numeral keys Tl of the typewriting machine to the master wheel 70 through the usual actuator or transmitting means, which I have not deemed it necessary to illustrate. It will be understood, however, that such transmitting means include the usual change gear construction by which the master wheel may be disconnected, or may be caused to turn in one direction or-the other for causing eorrespondin movement of the register wheels and dials for addition or subtraction. This change gear construction is controlled by hand at the will of the operator and may be set at will for either Add or Subtract or Disconnect, but for the purposes of the present invention it is deemed unneeessary to enter into a specific consideration of such mechanism, all of which is described in the \Vahl Patent No. 1,270,471.

The Remington accounting machine of the character disclosed in said \Vahl patent also includes cross totalizing mechanism, which will now be described. Only so much of this mechanism is shown as is necessary to arriveat an understanding of the features of mypresent invention in their cooperation therewith.

The supporting frame for the auxiliary having" its looped portion passing around a pulley 76*, as shown in Fig. 2. The power of this 'spring'is exerted to return the cross truck to :the right to the limitof its move ment-independently of the main carriage when theicross truckais freed from the main truck or carria, e, 'as'v will hereinafter ap pear. -The cross truckcarries one or more cross totalizers onesuch totalizer 78 being employed in the' presentinstance. However,one form of the present invention was devised for use-in a machine which employs a plurality of such cross totalizers, and for the purposeof the present invention it is immaterialhow many such cross totalizers are employed. 'Saidcross totalizer is constructeddike'the vertical totalizer, with the dials,-- sight-openings, and register wheels including the-wheels 79. These last mentioned wheels correspond to the wheels (37 in the vertical totalizeis, and are brought successively into mesh with a master wheel 80 as the cross truck advances StttlbltY-slt'l) with the main carriage when a vertical totalize'r is passing through thecomputing Zone. i

The key controlled actuating mechanism for the master wheel 70 of the vertical totalizers in theRemington accounting machine of the character shown in said \Vahl patent also operates the master wheel 80. A change gear mechanism including a shiftable gear wheel 81 also is employed for the cross totalizer, such change gear mechanism being adapted to be shifted automatically when a vertical totalizer enters the computing zone. The means whereby the automatic shifting of the gear change mecha nism for the cross totalizer is effected will now be described in detail.

\Vhen it is desired to have the gear change mechani m for the cro totalixer shifted lil automatically from the normal, or say Add position, to either the Subtract or Disconnect position as a vertical totalizer enters the computing zone in its movement with the main carriage, such totalizer will be provided with a cam 82 of greater or less depth, depending on its function to control the gear shift mechanism of the cross totalizer for Subtract or Disconnect. Should the operator desire to have the machine arranged for Add in the cross totalizer 78 when a' given vertical totalizer is in the computing zone, then the cam 82 on the corresponding vertical totalizer is detached; or if it be an adjustable cam, it is adjusted to inoperative position. Each cam 82 coacts with a follower 83 as a vertical totalizer enters the computing zone and depresses it a greater or less distance depending on the character of the cam, i. e., whether it be a cam of the greatest depth for setting the change gear for Subtract or a cam of less depth set to change the gear for Disconnect. The follower 83 is in the nature of a roller supported by a laterally projecting pin on the free end of a crank arm '84, mounted on the forward end of a rock shaft 85. Asa vertical tota-lizer passes out of the computing zone, the follower '83 and the parts controlled thereby are returned to normal position by a spring.

The intermediate connections between'the shaft 85 and the change gear mechanism of the cross totalizer will :now be described.

Referring first to Fig. 2, it should be understood that this figure shows the gear change mechanism of the cross totalizer, or the parts which automatically control it, in their normal positions. Said view shows a cam 82 about to coact with the follower 83 to bring about a depression thereof and automatically shift the change gear mechanism as the vertical totalizer which carries said cam 82 is about to enter the computing zone. Fig. 5 shows the positions of the parts after the change gear mechanisn'i has been shifted, and the vertical totalizer carrying the active cam 82 is about to pass out of the computing zone.

Referring to these two figures and to Fig. 6, which shows the parts disposed as they appear in Fig. 5, it will be seen that the rock shaft 85. which carries the follower 83, has its rear bearing in a fixed support 88, the same being the main frame casting of the calculating mechanism, and that said shaft extends through said support beyond the rear side thereof. The rea-rend of this rock shaft has a three-armed lever or member 89 secured thereto. One arm 90 of this member is connected to a contractile spring 91 which is the spring hereinbefore referred to as the restoring spring for this whole train of gear shift mechanism. A second arm 92 on the member 89 coacts with a stop pin 93, to limit return movement of the member 89 and the parts connected therewith to normal position. The third arm 94 of said member 89 has pivoted thereto, at 95, two parallel links 96 and 97 of like formation, each formed with a V-shaped notch 98 in the upper side thereof. These links are maintained spaced apart and are fixedly united to move together by suitable means such as a shouldered rivet 99. The bottom of the V-shaped notch is in the nature of a seat for a pin 100. This pin is carried by and projects laterally from the upper end of a lever 101, fulcrumed on a pivot 102. carried by a hand controlled link 103 and supported in the usual manner by a fixed bracket, not shown. The pin has a hub 104 provided with a flange 105, spaced from the upper end of lever 101to form a circumferential groove so that it may be received and guided in'a slot 106 in a fixed supporting plate 107. The lower end of the lever 101 is -prcw'ided with an angular slot 108 through which projects'a pin 109 carried by a crank arm 110. "This crank arm is fixed to the rear end of a rock shaft 111, which receives a bearing :in the support 88. The forward end of this rock shaft carries an upwanilyprojecting crank arm 112, pivotally connected at 113 to one :end of .alink 114. The opposite end of this link is pivoted at 115 to .a. :lever 116, tulcrumed at 117 on a bracket arm secured to the supporting frame. The lower end of the lever 116 is pivoted at 118 to a slide 119 by which the change gear mechanism is shifted.

As fully described :in the VVahl patent, hereinbefone referred to, there are two shiftable gears, the rear one being journaled on and sliding with the rod 119. The gear 81 shown in the drawing, is the forward gear which slides in the opposite direc tion to the rod 119.

From the foregoing description it will be understood that, assuming the parts to be normally in the position shown in Fig. 2, the entrance of a vertical totalizer in the computing zone will bring the companion cam 82 into co-operation with the follower 83, and depress it to the position shown in Fig. The effect of this is to rock the lever 116 through the intermediate train of connections from the Fig. 2 to the Fig. 5 position and automatically shift the change gear of the cross totalizer: shifting the gear 81 from the full to the dotted line position in Fig. 2. When the cam 82 runs off of follower 83, the parts move back to addition position.

In said Remington accounting machine if the operator should .desire to compute in. say, the last computing zone without actuating the preceding vertical totalizers this is ordinarily accomplished by depressing either of the ordinary carriage release keys moving the carriage by hand, say, from the extreme right-hand position to bring the right-hand totalizer, say 66, to the computing zone. This same result may be accomplished by successively operating one of the tabulator keys 36 until theve'rtical totalizer 66 is brought to the computing zone. The effect in either case 'is that the cams 82 on all of the preceding vertical totalizers 63, (34. and 65 will cause successive operations of the-gear change mechanism of the cross totalizer.' WVhen a large'number ofvertical totalizers are employed this unnecessary repeated back and forth operation of the gear change or gear shift mechanism, whenever the carriage is moved as stated, causes undue wear on the parts with'the possibility of injuring the mechanism by reason of the rapidity and force of the operations, and also results in the production of an unnecessary amount of noise.- It will be understood, moreover, that "this repeated unnecessary operation-ofthe gear shifting mechanism of the cross totalizer takes place during the return movement of the carriage, with the same liability of injury to the'ma chine. Such return movement of the carriage is usually effected with the aid of a combined line spacing and carriage return handle 120 which isconnected ma "rock shaft 121 and is'r'eturned to normalposition on the carriage by 'a spring 122, see Fig. 6. 1

It is one of the purposes of my invention to eliminate this unnecessary automatic operation of'the change gear mechanism during 'forward and back traveling movements of the main carriage, when such movements are effected in the manner set forth or in any manner except in the ordinary' step-by-step feed of the carriage under control of the letter or numeral keys, or the usual letter space key, as will hereinafter more clearly appear.

The means disclosed in the present instance for preventing unnecessary back and forth movement of the automatic shifting means for the change gear of the cross totalizer, is automatically controlled by the operation of any tabulator key 36, by either of the carriage release keys 20 or 25 and by the handle 120 in the manner which will now be pointed out.

The release keys 2t) and 25 are extended forwardly further than they are ordinarily. but. each is provided on the right-hand edge thereof with the usual upwardly turned flange 123 that assists the operator in moving the carriage to the right after the release key is first depressed to release the carriage. The outer face of each flange 123 is curved and I utilize each such face to coact with a cam to actuate the controlling mechanism. Thus. the outer face of the flange 123 on the key 20 courts with the inclined edge 12A of a cam member 125. A second inelinedface 126 on said cam member rests on the right-hand edge of the as sociated bracket 62. The cam member 125 has a carrying arm or off-set extension'127 pivoted at'128 to a horizontally disposed plate. bar or controlling member 129 that extends substantially throughout the length of the 'main calculator carriage or truck in the rear of the bar 58 thereof and forward of the fixed support 88. This controlling member 129 while it is connected to travel with'the typewriter carriage and the main truck, is mounted in a suitable manner to receive a movement relatively to the main truckm-Tn the present instance; the member 129 is provided with inclined s lots 130 at different points throughout the length thereof, which slots receive the reduced ends 131 of studs 132. The member 129*is held in place on jtlie reduced ends of the studs by headedscrews1131 screwed at their inner ends into tapped openingsfinstuds 132. The forward threaded" ends ofsaid studs are received in tapped openings in the truck bar 58, and said studsthus provide supports by which the member 129 is carriedby the bar 58 of the main truck. A contractile spring 133 is connected at one end to a pm 134 projecting forward from the member 129, the other end of said spi'in'g being connectedto a "pin 135 that projects rearwardlyfrom: the bar 58. The force of the spring is exerted to move the member; 129 on the main truck to the left, and by reason of the inclinedslots 130 such movement likewise compels the member to receive an upward movement to the normal position'shown in Fig. 2. lVhen, however, the release key 20 is depressed such movement cams the member 125 to the right and causes a. corresponding movement of the member 129, which also results in a downward movement of said member 129 to the operated positions shown in Fig. 5. A roller 136 extends beneath the lower edge of the controlling member 129, said roller being carried by a stud 137 that projects forwardly from a horizontally disposed lever 138. The right-hand end of this lever is pivoted at 139 on the fixed support 88. and is receivedin a cut-out portion of the front face of said support. as indicated at let-t) in Fig. 6. The lever 138 is pressed upwardly by a spring 141, anchored at its lower end by a screw 142 to the support 88. The power of this spring is exerted to maintain the roller 136 in contact with the lower edge of the controlling member 129, and to lift the lever 138 when the member 129 is moved to its normal elevated position. Depending from the lever 138 is a projection 143 that terminates in an extension 144 that projects to the left. Said extension 144 underlies an extension or contact 145 on a latch catch, pawl, detent, looking, or holding device 146. Said device is pivoted at its right-hand end, as indicated at 147, and in the present instance is in the nature of a gravity catch. An engaging projection 148 on said catch is adapted to extend behind and in the path of a pin 149 on the link 11 1 of the automatically actuated gear change shift mechanism, as indicated in Fig. 5, or to be held-out of the path of movement of said pin 1 19, as indicated in Fig. 2, which shows the parts in'normal position.

Let it be assumed that the typewriter carriage is at the extreme right, and that the operator desires to bring the extreme right hand vertical totalizer 66 to the computing zone without registering in any of the preceding vertical totalizers. The operator may depress the carriage release key 20, thereby lowering the controlling member 129 and forcing down the lever 138 against the force of its spring 141. The effect of this is to permit the gravity pawl or catch 146 to be lowered to the effective position. The feed rack 18 having beenreleased by the depression 'of the release key 20,, the operator may now movethe carriage to the left and when the cam 82 on the. first vertical totalizer 63 reaches the'computing zonefiit .-will depress the follower 83. and automatically shift the gear change mechanism from the Fig. 2 to the F ig., 51 position. .During such movement of the. parts the link 11 1:. will move from right .to. left, causingthe .pin 149 to be brought against therear beveled f-ace of the projectiong 148, .therebylifting the gravity pawl'.-1;16. hen said pin 'passes thel rojection 1&8 the gravity pawl. drops to e ective. position with the irpnt-face of the projection 148. engaging-behind the pin 149, preventing a return, movementof the link 114 and. a r eturn. of the. follower ;83 from its depressed position. This-results in locking the change gear mechanism, and the entire; train of connections from said mechanism to the follower, against return movement, as shown in Fig- 5-. .It follows therefore that the follower 83 will be maintained against return movement atthe lowcst point of its depression, and out of the path of any of the cams 82 on the succeeding vertical totalizers as long as the operator maintains pressure on the release key 20. The parts of the automatically shifting change gear mechanism will there fore remain quiescent instead of being shifted back and forth as each vertical totahzer passes through. the computing zone. \Vhen the totalizer 66 reaches said zone the operator releases pressure on the release key 20, the bar 129 and lever 138 are restored by their springs 133 and 141 to their normal upper positions. drawing latch 116 out of engagement with pin 149 and freeing the change gear mechanism. Said mechanism th'en assumes what.- ever position is appropriate to the column in use, depending on whether or not the particular vertical totalizer has a cam 82, and if it has, how deep a cam it is. The operator then proceeds to operate the numeral keys to register a number in the totaliZers 66 and 78. In the drawing, totalizer 66 is shown with a subtract cam, and the member would therefore be registered negatively in totalizer TS. \Vhen said totalizcr passes through the computing Zone, all parts of the gear shifting mechanism will be rcturncd to normal position.

I have provided corresponding means at the other side of the machine whereby the same results are accomplished should the operator depress the left-hand iclcusc key 25, instead of the right-hand release key. Thus, the outer right-hand curred face of the flange 123, on the key 25, coacts with the inclined face 150 of a cam member 151. This member rests upon the associated bracket 62 and is provided with an offset. extension 152, pivoted at 153 to the controlling member 129. It has hereinbefore been explained that. both the levers which carry the release keys 20 and 25 have an interlocking connection with. the feed rack 18, and. it follows therefore that both keys are connected through-said rack to move together. Both keys operating on their respective cam members to shift the controlling member 129 to the right and downwardlygfrom the normal position, it follows that an, actuation of either key 20 or 25 will produce the same results explained above.

. After a number has been set up in the last totalizer 66. asv described, and the operator desires to return the: carriage to, say, the extreme right, this may be done by maintaining pressure on either release key and moving the carriage to the right as previously explained. The pressure thus maintained on a release key holds the follower S3 in a depressed position as previously described. and maintains it. and the parts controlled thereby, out of action until all of the rertical totalizers have passed to the right over the follower S3, and the carriage is returned to the extreme right-hand position. It will be understood. therefore. that the gear shift mechanism is maintained out of :ulion during return movement of the carriage. as well as during the free forward niorcmcut thereof.

Sometimes the carriage is returned to th right by the combined carriage return and line spacing handle 120. In order therefore that the carriage may be returned with the aid of this handle without unnecessarilr operating the gear shift mechanism, 1 hanprovidcd means wlierebv an actuation of said handle automatically mores the ((M2- Lil trolling member 129 from the Fig. 2 to the Fig. 5 position. This effects the same results that are attained by depressing either of the carriage release keys 20 or 25. The handle controlled means referred to comprises a crank arm 154 secured to and extending downwardly from the rock shaft 121 to which the handle 120 is secured. This crank arm in its movement to the right from the normal position coacts with a pin 155 which projects rearwardly from the extension 127 of the right-hand cam member 125. ln returning the carriage with the aid of the handle 120, pressure exerted on the latter is effective to 'turn its rock shaft 121 before the carriage is moved to the right. 'lhis movement of the rock shaft carries the crank arm 154 from the full to the dotted line position in Fig. 5 and moves the controlling member 129 to the position shown in this figure.- When the rock shaftreaches the limit of itsturning movement'the carriage willsta-rt; to move to the right. The pressure of the operators hand on the handle is maintained 'until the carriage is fully returned to the right. Consequentlyzisuch' pressure willihold the controlling member 129 and the parts controlled therebyin the F iglif) position until the" return of the carriage vis completed. Vh'en this is accomplished the' operator releases the handle120 and its spring -122 will return it to normal positioln; permitting the controlling member. 129- and the: parts controlled thereby to retur n tonormal position.

It has been hereinbefore explained: that an actuat-ion of any of the t-abulator'keys '36 is effective to lift the feed rack l8g iand' liy reason of the connection between said rack and both carriage release keys '20 and 25 this will effect adepression' of the latterfl It follows, therefore; that an actuation of-any tabu'lator key" will move thercoht'rolling member 129 from the Fig. 2tothe'FigJ'5 position in the same manner asthou'gh said controlling member were actuated by either of the carriage release keysyor, the line spacing handle and said controlling memher will be maintained in its'operative position as long as the operator maintains pressure on the actuated tabulator key. When it is released and returns to' normal posi tion the release keys'20 and25,' the controlling member 129 and the parts controlled thereby will return to normal position. I 1

From the foregoing description it Will'be understood that automatically operating means are provided for throwing the auto matic gear shift mechanism out'of action on the operation of either of thejcarriage release keys 20 or 25, on a-ctuationof the line spacing and carriage return handle- 120, and on the actuation of any of the tabulator keys 36.

I have stated that in addition to automatically throwing; the change gearmechanism out ofoperatiomlalso provide automatically actuated means whereby the unnecessa'ry forward and. back jumping movements of the cross'totalizer are eliminated. with the undue wear, injury and noise which are apt to result from such unnecessary jumping movements of the cross totalizer and its truck. 'This construction will now be described, but before. describing these features ofmy invention it is necessary to describe the usual construction embodied in the Remington accounting machine as it is disclosed in said l/Vahl patent, with sufficient detail to arrive at an understanding of my invention in combination therewith.

Automatically operating connecting means betweeneach vertical totalizer and the cross truck or carriage are provided for intermittently picking-u tr the cross carriage and releasing'it, for alternate forward and backward movements during a single travel. of thevmain' truck or carriagein "one direction. This-mechanism isdisclosedin Fig; 4. i The right-hand side plate iofweach vertical totalizer is. formed :with an engaging projection 156,- which is adapted to coact with an upward-1y extending hook-like projection LOX" tooth 157 ona so-called pick-up beam 158. A laterally projectingdieaded screw stud 159, fixed to thebeam:158 is received in-a short-horizontallydisposed bearing slot 160 in a bracket arm 161;:sectired tothe 'cros's truck-74. This construction enables the beam 158 toreceivea pivotal movement on thbracket, and also affords a limited relative'fsliding movement between the two against the actioniof a contractile buffer 'spring162; connected atrone end/to a pin 163 carried I by the beam*158,-and at its other endt'o the bracket arm 161. Itwill be observed" that the force of the spring is directed in a line above the stud 159,- and therefore tends to turn'the beam around the centerbf said stud and elevate the inner lio0kearrying-end' of the beam, and also tends to maintain the stud seated at the right-hand'end of the'slot 160. This last. mentioned function ofthe spring is to provide a cushion between each connected verticalltotalizer and the cross truck as the latter is picked up by the former, especially in the rapid movement of the carriage under the action-of the tabulator keys, and when the carriage is moved-by hand.

A forwardly projecting pin 164 extends from the pick-up beam 158 F and p'rojects through a la-rge opening 165 in apick-up guard 166, to be hereinafter more specifically described. This pin 164 isprovided-with a guide flange 167'which coacts with the guard 166 at the front side thereof.

The pin 164, after passing through the opening 165 in the pick-up guard extends into=a slot 168 in a fixed plate 169. A part of the lower wall of the slot 168 is formed by the upper edge of an auxiliary plate 170 adapted to be adjusted along the plate 169-, and secured in place thereon by screws 171. The upper edge of the plate 170 has a depression 172 therein, which when the parts are in normal osition is beneath the pin 164. This permits the pin 164 to move down into the depression as the engaging projections 156 on the vertical totalizers move successively over the beveled face of the tooth 157 and depress the pick-up beam in the backward travel of the main carriage. The slot 168 throughout allother parts thereof is of a width which corresponds substantially to the diameter of the pin 164, and the walls of the slot thereforerestrain the pin against free up and down movement. The left-hand portion of the slot 168 is formed with a cam 173, with which the pin 164 coacts as the pick-up beam is carried along with the main carriage by a projection 156 on a vertical totalizer. The efl'ect of enga ing the cam 173: is to move the pin 164 and the hook-carrying-end of the beam down, thus disengaging the hook 157 from the totalizer, and. enablin the cross truck: and the beam to be returne to the right independently of the main track or carriage. The spring 76 is effective to bring about this independent return movement, of the cross truck and the parts connected therewith. In addition to the spring 162 for elevating the beam- 158 thereis provided the& usual lever 174 pivoted at 175 on a fixed pivot and connected. at. one end to a spring; 176. The contact nose 177 of this leveris arranged beneath and is adapted to bear against the lower edge of thepick-up beam 158, and tends to resist the downward disengaging movement thereof. A forwardly projecting car 178 on the lever 174, coacts with the under edge of the fixedplate 169 and limits the upward movement of the nose 177. The bottom edge of the pick-up beam 158 is so formed that it remains out of contact with the nose 177 of the lever when the pin 164 engages the cam 173, as shown in Fig. 4, to release the pin from the engaged vertical totalizer, so that, when said beam is depressed, it docs not have the resistance of the spring 176 to overcome.

The pick-up guard 166, hereinbefore referred to,. is provided to automatically coact at. its free end 179 with the right-hand face of the projection 156 on a vertical totalizer when the hook or tooth 157 engages the opposite side of said projection, and thus form an interlock that prevents a relative movement between the main truck and the cross truck in either direction of travel.

A complete detail description of the construction and operation of the pick-up guard is dceuwd unnecessary, except to point out that it is automatically actuated and oper ates in conjunction with the pick-up beam to insure the proper positioning of the cross truck in a decimal position corresponding to that of a vertical totalizer, when the latter is in the computing zone. This may be bet ter understood when it is pointed out that the pick-up guard 166 is pivoted on the stud 159 and is moved to its elevated engaging position by a Spring 180. When the cross truck returns, and the pick-up beam moves back to normal position, a cam 181, see Fig. 4, on the guard 166 engages a pin 182 which is in the path of the cam and is carried by a fixed plate 170. This engagement of the cam with the pin causes the guard member 166 to be lowered at its free end out of the path of the projections 156, l/Vhen, however. the pick-up beam is engaged by the projection 156 and moved to the left, the cam member 181 is moved away from the fixed pin 182. This enables the guard to be elevated by its spring 180 and the end 175) of the guard to be positioned to the right of the rojection 156 engaged by the hook 157. hen, however, the hook 157 is cammed down out ofengagement with the projection 156, as hereinbefore described the pin. 164 carries the guard 166 down with it.

It will be understood that ordinarily in the operation of the machine, as a vertical totalizer, say, 63, approaches the computing zone to bring a wheel 67 thereof into mesh with the master wheel 70, the pick-up beam 158 will be engaged by the projection 156 onsaid totalizer 63, causing the cross truck and the totalizer 78 to travel in unison with the main truck or carriage. As said totalizer 63. passes out of the computing zone, and

beyond the master wheel 70, the pin 164 reaches the cam 173 and releases the pick-up beam, thereby enabling the cross truck and the totalizcr 78 to be returned to the right by' the spring 76. This intermittent forward and back movement of the cross truck and the totalizer takes place as each vcrtical totalizer passes through the computing zone. even when no actuation of the vertical totaiizers is effected. This,-'thereforc, results in;unnecessar v forward and back movements of the cross truck and totalizer, with the consequent unnecessary wear. liability of injury thereto and the production of a claltering noise especially under the rapid mo\'c ments of the main carriage by band. or under control of the tabulator. 1101 it bc assumed for example that the main carriage s in the extreme right-hand position and the operator desires to operate only the last or fourth totalizer 66. It has hereinbclorc been explained that this may be effected by depressing either of the carriage release kcys 20 or 25 and moving the carriage down to the proper position by hand as is usually the case. (3r as is sometimes the case. the

result may be effected by operating the proper tabulator key, in the instance supposed, four times, thereby bringing the fourth totalizer 66 by successive jumps of the main carriage into proper position to be actuated. In the said Remington accounting machine, when the carriage is moved by hand to the desired point, and as the first vertical totalizer approaches the computing zone, the cross truck will be automatically picked up and carried with the main carriage until said vertical totalizer passes out of said zone, when the cross truck will be released and jump back to normal position. The alternate automatic icking up and releasing of the cross truck or return movement thereof is repeated as each vertical totalizer passes through the computing zone. Substantially the same result is brought about in said machine when the tabulator keys are successively operated to bring the last totalizer 66 to the computing zone. In the specific ex ample shown there will be six unnecessary forward and backward movements of the 1 cross truck to bringthe totalizer 66 into proper position Without actuating any of the preceding vertical totalizers. It should be remembered however, that as many as, say, thirty vertical totalizers are sometimes employed on long carriage Remington accounting machines, and'that to bring the lasttotalizer to proper position as supposed above would result in some fift -eight unnecessary rapid forward and back umping movements of the cross truck at each such selectionof the last vertical totalizer for'use. But by my present invention, these unnecessary jumping movements of the-cross truck are eliminated, thus saying a great amount of unnecessary wear o'n'fthe parts, liabilityof injury thereto and the elimination of the clattering noise due to such jumping of the truck. This result is attained in the present instance by the mere addition of alatch, locking device, pawl or detent183 to the automatically controlled lever 138. Said pawl is pivoted at 18 1 to a depending arm 185 on said lever, and is returned to and maintained in normal position with refer ence to said lever by a contractile spring 186, connected at one end to the arm 185 and at the other end to a projection 187 on said pawl. A laterally extending lug 188 is provided on the pawl, and said lug overlies the horizontal portion of the arm 185 to coact therewith, and limit the pivotal movement of the pawl under the force of its spring 186. In the present instance the lower part of the arm 185 is bent as shown in Fig. l to bring the dog 183 into an inclined position to engage properly with a convenient part of the bracket 161. The detent 183 is intended under certain conditions to engage the cross truck or any suitable part attached thereto or operatively connected therewith. In the present instance the engaging nose 189 of the pawl or detent 183 indicated in Fig. 2 is normally out of the path of the bracket arm 161, fixed to the cross truck and on which the pick-up beam 158 is mounted, as will be understood from an inspection of Fig. 1. lVhen the bar 129 is depressed as hereinbefore described the lever 158 will be lowered from the Fig. 2 to the Fig. 5 position as hereinbefore explained, carrying the detent 183 down with it. This brings the lower inclined edge .190 of the detent into the path of the bracket arm 161 and the carriage having been released will be advanced. Before the first vertical totalizer 63 reaches the computing zone the cross truck will be picked up and advanced with the main carriage. During this advance of the cross truck, the bracket 161 will coact with the inclined edge 190 on the detent and deflect it upwardly around its pivot 184, and against the force of the spring 186. As soon as the bracket 161 passes the free end of the detent, the spring 186 will snap the detent back to engaging position with the engaging nose 189 thereof to the right of and in a position to engage the right-hand face of the bracket arm 161 as shown in Fig. 5, thus preventing a return movement of the cross truck as long as the detent remains in this position, that is to say, as long as pressure is maintainedon a release key, which is. during the entire'forward travel of the'carriage necessary to bring the vertical totalizer 66 to: theconiputing zone. When this position h'as' been attained the operator releases pressure: on the depressed release key,. and thecontrolling member 129, the lever138 and the detent 183 ,are returned to normal position, shown inj'Fig. 2, where the detent [no longer offers an obstruction'to the return movement of the cross truck. However, with 'thelmain carriage in the position indicated, ready to register in thelast totalizer 66, theprojection 156 thereon will be positioned where the advanced pick-up beam' 158 will coact therewith as soon as the operator releases the depressed release key 20 or 25, thereby preventing a return :movernent of the cross truck to normal position. Asthe carriage advances in registering a number in thelast totalizer 66 the cross truck will be advance d with it and as the totalizer 66 passes out of the computing zone the pick-up beam will be automatically released and the cross truck will be returned to normal position. It will be seer therefore that thecross truck was advanced and returned to normal position only once, although the carriage carried all of the vertical totalizers through the computing zone and registered a number in the last totalizer 66. The same thing would occur under like conditions no matter how many vertical totalizcrs are employed. If, for example, thirty totalizers be employed and the same character of entry is to be made, there would be a single forward movement of the cross-truck and a single backward movement thereof to normal position insteadof sixty forward and backward movements, as would be the case ordinarily.

Should the carriage be in the extreme right-handpbsition and-the operator prefersto bring thelast totalizer 66 to thecomputing zone without registering in the pre ceding vertical totalizers, with the aid of a tabulator key, this may be done as follows:

The operator actuates'the proper tabulator key 36 preferably of a low order four times, thereby bringingthe fourth 'totalizer 66 by successivejumps of the main carriage into proper position to be actuated. Ordinarily the conse uence of jumping the main carriage in the manner described is to alternately pickup and release the cross truck for free return movement tonormal position for each 'ump of the main carriage, and there would be six unnecessary forward and back movements offtlie cross truck in the example specified, or fifty-eight such unnecessary movements if thirty 'totalizers were employe'cl i 1nder the sarne conditions. v It I will be understood, moreover, that ordinarily thepickfiip of; the erosjs'itruck in the manner indicatedis efi'ecte dwhile the main carriage is free durinqal tabulating operationaalid often when t e c'arri'age has runa considerable distancebefore the'piek-up of the cross truck isefi'ected an d at tiines when h crossr 'i'sru aing'i y ni efinp aiajdimi zsm..jr ri mhiplei skipp ng cere i nbS's' truf when eteasifi ir'om a yert'kcali totalizer ,thatis; a t'thetin e pass n 91 th pm ti g a-w l i p l the w ii 'a t ts l 'inda i nf t'fihe vertica itotalizers arespacei l sbii1e dis tance apart. I This unnecessary. jumping 'ba'ck of the cross truck results jn i 1nn e'ces s a1 'y wear and noise. If on the otherfhaiid ,the tot'aliz ers are close to ether then whenlh cross truck Jumps to t e right, it is'arrestedby the pick-up beam engaging the 'lu'gfl156 of the neigt, oncoming V total izer. 'As said oncoming yer tical totalizer is then moving rapidly towardlthe left-and the cross '-truck is moving rapidly to the rightfthe resulting blow on the comparati vely frailparts is apt to injure or strain thecons'truetion such for example as by breakingofl theprojection 157. t

In the present construction I overcome these diflieulties by automatically throwing the detent 183 into action at each operation of any tabulator key to hold the cross truck in its forward position as long as pressure is maintained on a tabulator key. It. has been explained that when the feed rack 18 is elevated by the operation of a tabulator key .to release the carriage. such movement of the rack through the interlocking connection at 23, 24 effects a depression of botll release keys 20 and 25. This is'eflective to brin about a lowering of the controlling member 129 and the parts controlled thereby from the Fig. 2 to the Fig. 5 position. This drops the detent 183 into effective position in t e same manner asi f the operation was effected by a release key. As the carriage moves forward to bring the first totalizer 63 to'the computing zone, the cross truck is picked up and moved to effective position in a corresponding decimal position, the detent 183 by this time being rendered effect; ive to hold the cross truck against return movement. \Vhen the tabulatingmovement of the carriage is completedthe operator releases the actuated tabulator key. This enables the parts controlled by the tabulator key to return to the normal Fig.2 position and withdraws the detent 183 from the path of the arm 161. However, the carriage in the tabulating jump carried the totalizer 63 forward to the computing zone b itndtjjfar enough to release the pick-u beam, which release occurs when the totalizer passes outof said zone. Therefore,'the connection of the pick-up mechanism will be maintained and the cross truck will not return. The nextoperation of a tabulat'orkey will a'cl vane'e the carriage and carry the ttotalizer 63 through the computing zone, briiigin 'the totali zer 64 to zone. :The effect of this is to release the 'cross truck from the pick-up mechanism, but atf'tlie time of su'cli release the cross'truck is held in forward position by thedetent 183. When the actuated tabula'tor key isrel e sd for the 's'econldflt ime t-he d i w no l fg rf h'Q' t a s. k, but at this time the-fcarriagellias advanced the second. t'ot:i,1i z er to the coniputinjg zone and in a position where tli'ep ek-up mechanism will coact withth e cross truck. The pick-up mechanism will theiefore pre vent a return movement of the cross truck to normal ositipmtho gh it inay attimes Clrop back two or three spaces, or far enough to permit the pick-up mechanism to engage the totalizer, 'in'the present instance the totaliz er Q54. At this time themai'n truck is at rest and the blow on the lug 156 is .a slight one. M So on it is with the remaining totalizers until the last vertical totalizer 3G isbroughtto the computing zone a number is registered inthis totalizer, and it passes out of the computing zone. The eross'truck will then be automatically released from control of the pick-up mechanism and will return to normal position.

Fromthe foregoing it will be understood that during the successive operations of the tabulator key-to move the carriage so as't-o convey all of the vertical totalizers ekcept the last through the computing zone, and to bring the last vertical, totalizer to the computing zone and register a number therein,

there is but one forward movement of the cross truck from the normal to the advanced positionindicated in Fig. 5,-and' that there is but one return movement of the cross truck to normal position.

It will be" observed, moreover, that the rendering of the gearchange mechanism ineffective to shift, and'the locking of the'cross truckagainst movement to normal position, are both automatically controlled by the controllingmember 29 and that'said member automatically controlled by the release keys 2() and 25, by the line space, by the carriage return handle 120 and by all ofthe tabulator keys 36. It Will'be seen, therefore, that all of the ordinary means, by which the-forward and back travel of the carriage may' be effected, except the letter space-movement thereof by the printing keys and the-letterspace keyyare effective to automatica-llycontrol the' cut-out of the gear change mechanism "and the'lock for the crossftruck. f

While 'I-"have described in detail one form of construction embo'dyiii 'ithe" present invention I'am aware that't iie invention may beern'bodied in various forms, and that certaiii" fe' 'tures thereof may be employed without others? 3 Eor example, while it may be desirable to fsilence-"thgear' change mechanism against"autoiiiatid actuation," valuable results are attained by merely silencing the cross truck; or holding it against 'return movement as described, and vice versa.
